Anyone use the Zip? I really want something portable as I travel with work and also youth hostel regularly. Is this any good? I'm confused why it says 2,500 lux but then 30mins treatment time versus the Brightspark which says 10,000 and 90 mins?
Just to add, if you don't recommend the zip what would you recommend? I ought to be on a tight budget but am prepared to spend a bit to get something that'll work well for me. I was looking at the Golite as a friend recommended it but that seems unpopular? I like the idea of the rechargeable battery for my YHA trips etc since there are no sockets in the rooms.
